HEATING- APPARATUS.

. To all whom it may concern:

Be it known that we, THOMAS H. WARD and RUFUS SEALS, citizens of. theUnited States, both residing at California, in the county of *Washingtonand State of Pennsylvania, have invented new and useful Tmprovements inHeating Apparatus, of which the following is a specification.

Our invention relates to apparatus for heating buildings with hot air orsteam or hot water or any two of these methods or all of them.

- It is the object of our invention tosimplify existing heatingapparatus known to us so that the consumption of fuel may be lessenedand that more of the heat generated by the burners may be utilized.

Referringto the accompanying drawings,

Figure 1 is a central vertical section or a'. heating apparatusconstructed in accordance with the principles of our invention, partsthereof being shown in side elevation; Fig. 2 a horizontal section onthe line Il[Ill of Fig. 1; Fig. 3, a plan of the air heating drum v;Fig. 4, a section of the line TV-TV of Fig. 1; Fig. 5, a section on theline VV of Fig. 1; Fig. 6, a section on the line V1[- 9 .,VI of Fig. 1;Fig. 7, a detail of the water heating apparatus .in connection with thefines for the products of combustion; Fig. 8,,a plan of the burners; andFig. 9, an elevation ofour improved apparatus with the external jacketshown in vertical section.

On the drawings,' 1 designates the vertical hollow base of our apparatusand contains the gasburners to. be described presently. 2 is a dooropening into the said space.

3 represents a hollow vertical steam-dome supported by the vertical rods4 standing on the base 1. 7 y

5 designates a number. of coils of pipe having their upper endsconnected to the lower ends of the pipes 6 which are secured in thebottom of the steam-dome 3 andcommunicate with the interior thereof. Thelower ends of the coils 5 are connected to the horizontal manifolds 7lying at. opposite sides of the coils. The rear ends of the manifoldsare, in communication by means of the series of pipes'8. Water issupplied to, these manifolds by the vertical pipes 9 which constitutethe lower end of the return system for the Water or condensed steam.ir'rom'the radiators which are supplied with water onsteam'by means ofthe pipes 10 leading from the top of the.steam-'dome.

In the base 1 we provide a circular series of burners 12 supplied withgas through the pipe 13, these burners being located below the coils 5soas to heat them most advantageously. \Centrally located within the coils5 is the vertical pipe or cylinder 14 containing the vertical water coil15 having its upper andlower ends connected by the pipes '16 and 17 tothe hot water boiler 18 in the usual or any desired manner.

The steam-dome has the central vertical flue 19 extending somewhat abovethe upper surface of the dome and provided at the lower end with theinternal shoulder 20.

21 is a vertical pipe having at its upper end the flange 22 resting onthe shoulder 20. The pipe 21 extends down into the flaring upper end ofthe pipe or cylinder 14.. This construction prevents the hot products ofcombustion from passing directly from the coil chamber into the flue 19and causes the said products to extend to the upper end of the coilchamber and then to curve down 27 and bottom 26, for the products ofcombustion. 28" represents an elbow-shaped flue which leads the productsof combustion from the flue 19 through the cylinder 25 into the annularspace between the cylinders 24: and

lar space is divided by horizontal partitions 29 and'30 into threehorizontal passages 31, 32, and 33. The passage31'has one end 25 andnear the bottom 26. The said annu- 1 closed by the partition .34 whichconnects the bottom 26 and partition 29;: The other end of the passageis closed by the said partition 34'but communicates with the pasv sage32 by means of the space 35 left in the partition 39.

41 indicates a damper in the smoke pipe 40. The radiator 23 issupportedby the legs 42.on'the top. of the steam-dome.

If our invention is to be used as a steam and hot air heater -water willbe supplied to the lower portion of the apparatus leaving more lessspace in the dome 3 for steam. The flames and hot gases from the burners12 willcirculate through the coils and pass down into the flared portionof the pipe '14 and then up the pipes or flues 21, 19, and 28 into thepassage 31, from which they pass through the passages 32 and 33 and intothe smoke pipe 40. Steam passes up the pipes 10 to the radiators of thehouse heating system and the condensed steam returns to the manifoldsthrough the pipes 9. More or less of the heat from the burners 12 passesoutwardly through the jacket 11, the steam-dome 3 and through theradiator 23 into the space 43 inclosed by the cylindrical jacket 44extending from the base-plate 45 to a short distance above the radiator23, the upper end of the jacket 44 being provided with the cover 46. Thehot air in the space 43 is led to the hot air registers of the househeating system through pipes connected to the hot air outlet pipes 47which extend through the up per end of the jacket 44.

if our heating .apparatus is to' be used with a hot waterheating systemthen the coils 5, the steamsdome 3, and the pipes 9 as well as all theother parts of the system will be-filled with water. Ordinarily when theburners 12 are in use the water coil 15 will be to supply water to theboiler use. Butin thesummer when the burners 12 are not in use theburner 48 will be lighted to heat the coil 15.
